A Fast Two-Stage Bilateral Filter Using Constant Time O(1) Histogram Generation

Sensors, 2022
Bilateral Filtering (BF) is an effective edge-preserving smoothing technique in image processing. However, an inherent problem of BF for image denoising is that it is challenging to differentiate image noise and details with the range kernel, thus often ...
